* [IA64] - SGI SN hwperf enhancements -Mark Goodwin2005-08-241-20/+246
| | | | | | | | | Add a new exported function for determining the nearest node with CPUs for I/O nodes and fix a bug where the hwperf dynamic misc device was being registered before misc_init(). Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] - SGI SN hwperf enhancements - export_pci_topologyMark Goodwin2005-08-241-34/+16

* [IA64-SGI] - New SN hardware support - ptc_fixesJack Steiner2005-08-172-27/+242
| | | | | | | | | | | | Shub2 provides a much improved mechanism for issuing internode TLB purges. Add code to support the newer mechanism. There is also some debug code (disabled) that is useful for testing. Collect statistics on the number, type & duration of TLB purges. This data will be useful for making future improvements in the algorithms. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

* [IA64] sparse cleanup of shub_mmr.hPrarit Bhargava2005-06-281-0/+1
| | | | | | | | | | | | | | | This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig and the sn2_defconfig config files. The issue with this file was the missing usage of __IA64_UL_CONST wrapper. This wrapper is defined in include/asm-ia64/types.h and wraps a long constant definition with UL or with nothing depending on its usage in the kernel. The missing wrapper caused many sparse compile errors like warning: constant 0x0x0000000010000380 so big it is long Signed-off-by: Prarit Bhargava <prarit@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64-SGI] Altix SN add support for slots in geoid_t locatorMark Goodwin2005-04-251-47/+24
| | | | | | | | | | | This patch against ia64-test-2.6.12 is needed for forthcoming Altix chipsets. It renames geoid_any_t to geoid_common_t and splits the 8bit 'slab' field into two 4bit fields for 'slab' and 'slot'. Similar changes in the Altix SAL will retain backward compatibility for old kernels. Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64-SGI] Altix SN topology fix potential infinite loopMark Goodwin2005-04-251-5/+7
| | | | | | | Fix infinite loop if sn_hwperf_location_to_bpos() fails. Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64-SGI] Altix SN topology support for new chipsets and pci topologyMark Goodwin2005-04-251-9/+124
| | | | | | | | | | | please accept this patch to the Altix SN platform topology export interface to support new chipsets and to export PCI topology. This follows on top of Jack Steiner's patch dated March 1st ("New chipset support for SN platform"). Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* Linux-2.6.12-rc2Linus Torvalds2005-04-1610-0/+1742
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
